Display device

Abstract

A display device includes a main body including a display module for outputting an image, a bending module located at a center of a rear surface of the main body, a pair of links respectively extending in left and right directions, wherein one end of the link is coupled to the bending module, and link brackets respectively located at left and right ends of the main body, wherein the other end of each link is connected to each link bracket, the bending module changes an angle of the pair of links, and, when the bending module is driven, the other end of the link slides horizontally with respect to the link bracket. The display device is able to switch a state of the display module into a flat state or a bent state, so that a user is able to use the display device in a desired shape.

The invention claimed is: 
     
       1. A display device comprising:
 a main body including a display for outputting an image; 
 a bending assembly located at a center of a rear surface of the main body; 
 a pair of links including a first link and a second link, 
 wherein the first link extends along a leftward direction, and 
 wherein the second link extends along a rightward direction, and 
 wherein one end of the first link and one end of the second link are coupled to the bending assembly; and 
 link brackets including a first link bracket and a second link bracket, 
 wherein the first link bracket is located at a left end of the main body, 
 wherein the second link bracket is located at a right end of the main body, 
 wherein the other end of the first link is connected to the first link bracket, 
 wherein the other end of the second link is connected to the second link bracket, 
 wherein the bending assembly is configured to change an angle of the pair of links, 
 wherein, based on the bending assembly being driven, the other end of the first link slides horizontally with respect to the first link bracket, and the other end of the second link slides horizontally with respect to the second link bracket, 
 wherein the first link includes a first moving bar located on a surface facing the first link bracket at the other end of the first link, 
 wherein the second link includes a second moving bar located on a surface facing the second link bracket at the other end of the second link, 
 wherein the first link bracket includes a first link side block in contact with the first moving bar, 
 wherein the second link bracket includes a second link side block in contact with the second moving bar, and 
 wherein the first moving bar and the second moving bar are configured to slide within the first link side block and the second link side block, respectively. 
 
     
     
       2. The display device of  claim 1 ,
 wherein the first link side block includes: 
 a first slide portion parallel to the rear surface of the main body; and 
 first side walls located at a top and a bottom of the other end of the first link, and 
 wherein the second link side block includes: 
 a second slide portion parallel to the rear surface of the main body; and 
 second side walls located at a top and a bottom of the other end of the second link. 
 
     
     
       3. The display device of  claim 2 ,
 wherein the first moving bar includes: 
 a first friction portion protruding toward the first slide portion; and 
 a second friction portion protruding toward one of the first side walls, and 
 wherein the second moving bar includes: 
 a third friction portion protruding toward the second slide portion; and 
 a fourth friction portion protruding toward one of the second side walls. 
 
     
     
       4. The display device of  claim 3 , wherein the first link side block, the first moving bar, the second link side block and the second moving bar comprise polyacetal (POM: Poly Oxy Methylen). 
     
     
       5. The display device of  claim 4 , wherein a hardness of the first moving bar is greater than a hardness of the first side block, and
 wherein a hardness of the second moving bar is greater than a hardness of the second side block. 
 
     
     
       6. The display device of  claim 1 , further comprising:
 a first bracket fastener for fastening the main body with a first portion of the first link bracket located at a first horizontal end of the display device; and 
 a second bracket fastener for fastening the main body with a first portion of the second link bracket located at a second horizontal end of the display device, 
 wherein a second portion of the first link bracket located at a horizontal center of the display device and a second portion of the second link bracket located at the horizontal center of the display device are not fastened to the rear surface of the main body. 
 
     
     
       7. The display device of  claim 6 , wherein, based on the main body being bent, a gap between the second portion of the first link bracket and the rear surface of the main body is widened, and a gap between the second portion of the second link bracket and the rear surface of the main body is widened. 
     
     
       8. The display device of  claim 1 , wherein a rear surface of the first link bracket includes a first inclined surface rearwardly extending from a first horizontal end of the display device toward a center, and
 wherein a rear surface of the second link bracket includes a second inclined surface rearwardly extending from a second horizontal end of the display device toward the center. 
 
     
     
       9. The display device of  claim 1 , wherein the first link bracket includes a first stopper for restricting the sliding of the first link, and
 wherein the second link bracket includes a second stopper for restricting the sliding of the second link. 
 
     
     
       10. The display device of  claim 1 , further comprising a first bracket cover for covering the first link bracket and a second bracket cover for covering the second link bracket,
 wherein the first bracket cover is configured to restrict a movement of the first link towards a first horizontal end of the display device, and 
 wherein the second bracket cover is configured to restrict a movement of the second link towards a second horizontal end of the display device.
